Description
Due to shortages of IPv4 address space - real or artificial - many HEP
computing installations have turned to NAT and application gateways.
These workarounds carry a high cost in application complexity and
performance. Recently a few HEP facilities have begun to deploy IPv6
and it is expected that many more must follow within several years.
While IPv6 removes the problem of address shortages and its painful
workarounds, it comes at some initial price in software and network
infrastructure evolution.
Routers and host protocol stacks have been ready for IPv6 for quite
some years, many major backbone networks carry IPv6 and peer with each
other, and site network management applications are available. Now
application and security considerations are on the critical path to
full exploitation of IPv6. We examine the steps required for grid
applications (storage and computation) and security mechanisms and
site network infrastructure (DNS, DHCP, access control policies) to
move to a mixed v4/v6 environment.
Summary
Requirements for moving grid facilities to mixed IPv4/v6 operation.
